Watts	Lumens	Life(hours)	Color K
55w Halogen	1450	675	3000
100w Halogen	2200	250	3000
130w Halogen	2750	100	3000
35w HID	3220	3000+	4300
50w HID	4350	2500	4300

As you can see, the amount of lumens per watt is almost 4x a standard halogen light.

Please see the pictures below for a visual explanation of the chart.

These lights were taken with a single bulb in a PAR36 reflector.  The PAR36 reflector is the standard reflector

used in almost all GA aircraft made since WWII.  It measures about 4" across and is just about the perfect size for most wing and cowl lights.

All our pictures are untouched.  We don't use photoshop to sell lights, we don't need to.  All pictures were taken at same apature and shutter.

The difference between a 35w and 50w HID.
